Term of Life

Spinach can be grown throughout the year, anywhere, either in the lowlands, and in the highlands. The best growth on fertile soil and lots of light sun. Good temperature 25-35 C and pH land between 6-7. The best planting time in beginning of the rainy season or early in the season dry.

Soil processing

Groundbreaking for the spinach as deep as 20-30 cm and fertilized enclosure or compost that has become a lots of 30-40 kg / m 2 or 30-40 tons per Ha. Soil and fertilizer should be mixed evenly to the soil loose. after the soil flattened, made beds, beds plant width from 1 to 1.5 m high as 12-15 cm and the distance between beds of with the other beds 30-40 cm.

Planting

Before the spread in the plot, smooth spinach seeds are mixed with dry husk ash or sand as much as 10 times the amount of seed to well blended, then spread in the groove line longitudinal inter-row spacing of about 20 cm. The number of seeds required for every 10 m2 bed about 10 grams,so for the Ha seed takes about 10 kg. 1000 grain weight of seed red Spinach average 0.59 g, and seed white spinach about 0.68 gr. Seeds that have been deployed, should be closed with fine soil or manure ripe. Better yet, when closed with a layer of straw. Usually 3-5 days after the seeds being spread the seeds germinate. Once the seeds begin to grow, ground cover must be opened.

fertilization

Manure is given a dose of 10 tonnes / ha or 1 kg/10 m2 when soil conditions less fertile / organic ingredients low. Given artificial fertilizers is 120 kg N / ha, 90 kg / ha P2O5 and 50 kg / ha K2O or equivalent of 30 g urea, 20 g of SP-36 and 10 g per m2 wide bed. Fertilizer is spread evenly and stirred on the bed, then leveled the ground in the beds.

maintenance

Spinach needs water to 4 mm2 or 4 liters per day at the time plants still young until first week, but when the plants going mature, these plants need water about 8 mm2 or 8 liters per m per day. Types of pests that often affects spinach include leaf caterpillar, aphids, leaf snorer and grasshoppers. If forced to use Insecticide use a type of safe insecticide and easy to unravel as insecticide biology, or plant-based insecticides. while disease is usually less harmful spinach plants, especially if environmental conditions around the planting maintained as good drainage, light

solar maximum and fertilization are not too much. Diseases that often found was collapsed germination (Rhizoctonia solani) and white rust disease (Albugo sp.)

Harvest and Post Harvest

Spinach is usually at harvest if the height has been reached about 20 cm, ie at the age of three up to four weeks after crop grow. This plant can unplug by roots or by cutting at the base average 2 cm above the soil surface. As for the spinach usually begin to reap the harvest in ages between one and a half months plucking week intervals all. Spinach plants are maintained well can produce up to 5 to 10 t / ha.
